JOSEPH A. IVEST, OF SAN RAFAEL, CALIFORNIA.

VEHICLE-SEAT.

SPECIFICATION forming part of Letters Patent No. 396,250, dated. January 15, 1889.

Application filed December 6, 1887. Renewed November 19, 1888. Serial No. 291.305. (No model.)

To all wwnt t may concern:

Be it known that I, JOSEPH A. IVEsT, a citizen of the United States, residing in San Rafael, in the county of Marin and State of California, have invented a new and useful Spring-Back for Buggy-Seats, of which the following is a specification.

My invention relates to improvements in a combined arm-rest and spring-back for buggy-seats, which will be understood by refer-A ence tothe accompanying drawings and the letters referring thereto.

Figure l is a side elevation of a buggy with my improvement attached. Fig. 2 is a side elevation, partly in section, showing my improvement attachedto a broken part of a buggy-seat.

A represents a buggy-seat; B, the springback; O, the supportin g-springs D, the stationary coupling; E, the connecting-rod, which connects the armrest or seat-rail with the front of the seat; F, the sleeve by which the arm-rest or seat-rail is connected and adj usted; G, the seat-back spring, which gives elasticity to the seat-back; II, the adjusting coupling, which connects the arm-rest or seat-rail with the rod J for the purpose of connecting the spring-back.

I represents the pivot or joint by which the arm-rest or seat-rail is connected with the spring-back.

J represents the rod or part of the seat-rail which connects with the spring-back.

K represents the recess to cover the thread upon the inner part of the arm-rest or seatrail.

L represents a stop on the end of the rod E, forming the bearing of the spring G.

The following is the construction of my improved combined arm-rest or seatrrail and spring-back.

I form the sleeve F and couplings D and H of brass or other metal capable of receiving a neat finish. I cut a thread in the coupling' H to receive the rod J, and I connect the coupling D by forming a smooth hole for the rod .E to pass through. The end of the -rod E has a stop to receive the bearing of the spring G. I cut a thread on the rod J to operate in the coupling` H, for the purpose of adjusting the seat-rail, as will be shown. I form the spring-braces C of the best springsteel.

The following is the operation of the invention.

The spring-braces C, forming the support of the back B, are firmly attached to the same and also to the seat A. The joint I allows the required play to adjust to the vibration of the back-supporting springs O, and as the seat-back is pressed the springs yield, the spring G allowing the rod E to draw out in proportion to the weight or force applied. This arrangement allows an elastic and perfectly easy seat-back. WIhen it is necessary to tighten or stilfen up the spring-back, the sleeve F and connecting-couplings I-I and D are revolved. The coupling II, operating' upon the thread of the rod J,lengtl1ens or shortens the seat-rail, and consequently renders the same more or less elastic, as required.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

In combined seat-rail and spring-braces for buggies, the combined seat-rail f and back, composed of the rods E and J, connected by the couplings H and D, the sleeve F, and spring G, in combination with the springback B and spring-supporting braces C, constructed and operated substantially as and for the purposes set forth.
